ADAPTER FOR LAMP SHADES.

Application filed April 13, 1922. Serial No. 552,157.

To all whom t may concern:

Be it known that I, JOSEPH HASLER, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented a. certain new and useful Improvement in Adapters for Lamp Shades, of which the following is a specification.

My invention relates to that class of shades which are designed to beattached to the standard holder. It is well known that the diameters of the standard holders are very much less than the diameter of the high powered gas lilled lamp bulbs r which are used so largely in commercial lighting. As a result when a shade is provided with a lip to be held by the thumb screws of the standard holder, it is impossible to pass a large bulb through the opening at the top of the shade. As a result in silk shades,`it becomes necessary to leave the bottom of the shade open and provide it with a draw string or other means so that the lamp can be screwed into the electric light socket after the shade is in position and the draw string then pulled closing considerable opening at the bottom of the shade. This necessitates the handling by the workmen of the silk with the result that it is frequently soiled.

Then, too,'when it becomes necessary to change the bulb, the draw string has to be untied and the'shade opened, all of which is expensive in time and undesirable, especially where shades oi light silk are employed.

l/Vhere glass shades are employed they have to make the opening large enough to admit the larger sized electric lamp bulbs with the result that the same cannot be used with the standard holder but has to be mounted upon special holders. v

My invention has for its object to provide a holder which will entirely obviate the foregoing objectionable features and will make it possible to suspend a silk or other shade having an opening large enough to accommodate the highest powered lamps and yet can be secured to the standard holder.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the drawings which are hereunto annexed and are a part of the speciication, in which Fig. l is a vertical sectional view of my improvement secured to a standard holder which is indicated in dotted lines as obviously it forms no part of my invention.

Fig. 2 is a detail view in elevation show ing the cap.

Fig. 3 is a detail 'View in elevation show7M ing the shade holder.

Fig. 4l is a top or plan view of the same.

Fig. 5 is a view oiE a complete shade equipped with my improved holder in which the lower part of the Shade is Secured by a draw string. y

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawing, my invention comprises a cap, l, which has a downwardly depending flange 2 which is provided with threads and a central opening 3, the edges of which extend upwardly and outwardly forming a lip 4 which is adapted to receive the thumb screws 5of the standard holder 6.

The shade holder comprises an annulus 7 which is provided with threads 8 which are iitted to the threads forming a downwardly depending flange 2 in the cap. The annulus 7 is provided with a radially eX- tending flange 9 to which may be soldered the wire frame for supporting the silk l0 where a Silk shade is used.

l/Vhen a glass shade is used, the lip thereof, is provided with threads corresponding to the threads 8, and fitted to the threads on the depending flange 2 of the cap l.

It will be apparent from the foregoing description that all that is necessary to do is to screw the cap upon the threads 8 of the annulus 7 and the shade is held in position. At the same time the inner diameter of the annulus is su'iiciently large to per mit the entrance or' a high powered electric lamp bulb. When it is desired to change the lamp, all that is necessary to do is to unscrew the two threaded members when access can be readily had to the lamp bulb without the necessity or' removing the cap from the holder.

Having described my invention what I regard es new and desire to secure by Letters Patent is:

In combination with L standard shade holder an adapter comprising a, oep having' a 'flange lip eng-ging the screws of the standard shade holder and provided with u lower threaded flange, a threaded annulus, to engage the threaded flange of the oep, provided on its lower portion with an outwardly projecting Wire frame and a shade mounted over the annulus and suspended from the Wire frame.

In testimony whereof, I have signed the Yforegoing speeoation.

JOSEPH HASLER.
